"White" Indians in Patagonia


Diego de Rosales, a Jesuit missionary and historian, wrote a history of Chile (Historia general del reino de Chile. Flandes Indiano) in 1674 (online here). In it he mentions bearded white Natives:


"In the part of Chile that has cold land, three are white Indians and in the Chonos I have seen them so white that they look like Spaniards. And, additionally next to the Strait of Magellan, there are with beards, and white, that if they dressed with Spanish clothes, they would all be judged [unintelligible] and of Europe [unintelligible] men so dark, that compared with these Indians, they look like Indians, and the Indians, Spaniards."

Could the white bearded men have lived here? Source

De Ovalle also mentions an expedition along the southern coast of Chile, that took place in 1640 when Diego de Vera advanced by sea towards the Strait of Magellan (source) in search of the City of Caesars.


"They caught a naked bearded indian, tall... they assured him that they wouldn't hurt him, that they wanted to know where were the Spaniards that they heard lived in the region of the Strait [of Magellan], to which sometimes he answered that there, were the Viracochas, called so becaus that was how they named the Spaniards in that region, taking from the Indians of Pery the name that they gave to the Spaniards, calling them Viracochas after their God Viracocha; and on other times he said they were already dead... and they found an Indian woman, who told them that the Spaniards they had seen were whiter and had fairer hair then them. And that the Viracochas that they knew were those of the territory of that indian. That like him, and those of his territory, they were bearded, so they looked like Spaniards, they called them with the same name they gave the Spaniards: Viracochas."


Viracocha is a Quechua word, and it was used by the Inca people of Peru to designate their creator god. Viracocha was the creator of earth, humans, and animals. The Inca spread their religion into Chile when they occupied North Central Chile up to the Bio-Bio River in the late 1400s. defeating the Mapuche.


City of Caesars


The “City of Caesars” was an “El Dorado” located in Patagonia. We can be summarize it as follows: The legend of the City of Caesars began in the mid 16th century. When a Spaniard named César reported finding a city of incredible wealth in South-Central Argentina.
The myth revolved around an incredibly rich city that some believed was set in the hidden mountains of western Patagonia. Its roads were paved with gold, and the kitchenware was silver.
It was inhabited by people of European origin who led secluded lives there. In some variants they were Spaniards, survivors of shipwrecked expeditions on the Strait of Magellan, who allied with the Tehuelches built their city on an island in a Patagonian lake around 46° South. In others they were Inca princes who had escaped the Spanish conquest and built their new empire in Patagonia.
Several expeditions were sent to find it, and it was not until the late 18th century that it lost credibility and searches were discontinued.

Waves can fool you (Lake Panguipulli)


The wind in Patagonia is strong and turns up unexpectedly. When it does, it can stir up a wave front on a calm lake like the one shown in the video below (online).


The video posted on Instagram was jokingly titled "Mounstro del lago Panguipulli" (Lake Panguipulli Monster), and all the comments joke about it being waves, a wave front, kurruf, which is the Mapuche word for wind.


The lake is set at low altitde (140 m - 460 ft.), and is almost 30 km long (18.50 mi.), its maximum widht is almost 15 km (9.2 mi.) it covers an area of 117 km2 (45 sq.mi.) and reaches a depth of nearly 270 m (880 ft.), its name means "Land of pumas".



Just waves. No monster.

Sites in Chile show Human activity 17.3 to 12.8 Ky ago


Arecent study published in 2024 (Pérez-Balarezo A, Pino M, Navarro-Harris X, et al. Revised pre-Younger Dryas chronocultural sequence at the Pilauco site, north-western Patagonia (40°–44°S). Antiquity. 2024;98(399):e16. doi:10.15184/aqy.2024.29) reported an older than expected date for stone tools in Patagonia.


These tools were dated to "17,300–12,800 cal BP, which indicates human presence in north-western Patagonia prior to the Younger Dryas period.."


The stone tools were obtained from two sites located in Pilauco and Los Notros, in the Chilean Lake Region in northern Patagonia, close to the city of Osorno.


The Younger Dryas was took place roughly 11,700-13,000 years ago during which the Northern Hemisphere cooled significantly while there was a warm period in the Southern Hemisphere. The Last Ice Age was coming to an end, but there were variations in the weather on a global scale, with rainfall pattern altered, global cooling, glaciers advancing in the North, but retreating in the South.


This finding is significant because it shows that modern humans were present in Chile at least 3,000 years before the currently accepted dates. This suggests that humans reached America much earlier.

Humans present in Argentina 20,000 years ago


Astudy that I have just come across (Del Papa M, De Los Reyes M, Poiré DG, Rascovan N, Jofré G, Delgado M (2024) Anthropic cut marks in extinct megafauna bones from the Pampean region (Argentina) close to the city of Buenos Aires, during the last glacial maximum. PLoS ONE 19(7): e0304956. https://doi.org/10.1371/journal.pone.0304956), reported bones with cut marks produced by humans that date back to roughly 20,000 years ago.


This pushes back the date of arrival of humans in South America, and may imply that the dates for humans crossing Beringia are too recent, and have to be revised.


"In this study, we present the analysis of fossil remains with cutmarks belonging to a specimen of Neosclerocalyptus (Xenarthra, Glyptodontidae), found on the banks of the Reconquista River, northeast of the Pampean region (Argentina), whose AMS 14C dating corresponds to the Last Glacial Maximum (21,090–20,811 cal YBP). Paleoenvironmental reconstructions, stratigraphic descriptions, absolute chronological dating of bone materials, and deposits suggest a relatively rapid burial event of the bone assemblage in a semi-dry climate during a wet season. Quantitative and qualitative analyses of the cut marks, reconstruction of butchering sequences, and assessments of the possible agents involved in the observed bone surface modifications indicate anthropic activities. Our results provide new elements for discussing the earliest peopling of southern South America and specifically for the interaction between humans and local megafauna in the Pampean region during the Last Glacial Maximum."

1923 Plesiosaur images


The media furor that resulted from the reported sighting of a live plesiosaur in Patagonia in early 1922 led to a massive coverage of the expedition sent to hunt it.


Of course, the creature didn't exist (at least not as a gigantic reptile), and the party sent to capture it returned to Buenos Aires empty handed.


Magazine cover with the Patagonian plesiosaur.

Caras y Caretas and an article (March 1922).

But a local tycoon, Don Primo Modesto Capraro (1873-1932), who had migrated from Belluno, Italy, to Argentina and settled in Bariloche, decided to have some fun with the episode.


For the 1923 carnival parade in Bariloche he built a float in the shape of a plesiosaur, using a wooden frame covered with painted burpap. He mounted the enormous structure on a truck and paraded down Mitre Street to the amusement of the locals. Capraro rode on a horse, dressed as the gaucho Martín Fierro, heading the parade. A group of people wearing costumes parodying the expedition members marched beside the float.


He promoted the parade with a mocking telegram sent to the media on February 19, 2023 that announced: "The plesiosaur was finally captured. Since yesterday it is blocked so it can't escape from the Bariloche beach. It was caught thanks to the "dry law" [prohibition of alcohol."


Carnival Float in Bariloche, 1923.

The animal's neck and tail were mobile, thanks to an internal mechanism in the float. The neck had stood upwards but was lowered so that it could pass under the lighting cables that crossed the street.


Capraro had made a fortune with his sawmill and had built most of the buildings in Bariloche. But the Great Depression of 1930 left him bankrupt. He committed sucide in 1932.

Lake Vidal Gormaz creature


Lake Vidal Gormaz is located in Chile, in the area between Puerto Montt, Chiloé Island, and Bariloche and El Bolsón in Argentina (see it in Google maps).


It is a long, narrow lake, 7.8 km by 0.8 km (4.9 by 0.5 mi.) it drains into the Manso River that comes from Argentina, with the outflow of several lakes including Lake Mascardi, the waters end up in the Pacific Ocean along the Puelo River.


We had mentioned it in our post on the Reloncavi region's monsters, and found another reference, quoted below: (online here)



"While we were there, more precisely at its northern tip, we found out about disquieting news . Like Nahuel Huapi who has its "Nahuelito", and other Southern lakes the famous "cuero", Vidal Gormaz also has a tennant, a supposed "monster". At least that is what the members of the Bahamonde family -legendary settlers in the area- told us, seriously. And there is more. A few months after this expedition, and because we mentioned this rumor in a post, they have written to me to tell me that in the Las Rocas Lake (located south of the Vidal, and in the same basin) there have been reports on this matter."

The lake is quite inaccessible, and set in the middle of the Andean forests. There is a fishing lodge on a farm on its southern tip.

On the Giant Sloth (an article from 1903)


An article published in "The Saint Paul Globe" (St. Paul, Minn.), on 8 February 1903 that can be seen online here, reported about the progress of Hesketh Prichard's expedition in search of the Mylodon (1900/1901) criticizing him for not exploring the deeper parts of the Andean forests.


It also mentions an encounter with a Patagonian Sloth, which took place around 1893, as follows:


Unless our memory serves us a trick, some half a score of years ago a party of explorers in Patagonia, among whom was a distinguished attache of a German university, encountered a monster answering perfectly to the description given by scientists of the Mylodon.
According as I remember the account to have been published in both American and European papers there were three scientists in the party and but one of these survived to tell the story of their adventures in Patagonia.
The German, according to this report, fell a victim to the mysterious reptile or mammal which was taken for the sloth and which was encountered in some vast virgin solitude on that inhospitable plateau of the Andes described by some who have been there as being beyond the possibility of actual words to convey its desolateness.
Whether it was a mirage of the pre-tertiary fossil which appeared to the travelers, for mirages are as plentiful in Patagonia as leaves in Vallambrosa, [Italian monastery, surrounded by forests. Ed.] or whether it was an actual great sloth, for these monsters might have retired to the fastness of such a remote region and even have their habitations yet in some of the vast caverns of the mountain ranges, cannot be told.


I haven't been able to find any refrence to an expedition with a Geman University member, but I did find the following note in an article published in the Buenos Aires Caras y Caretas magazine (No. 32, May 5, 1899 - online) written by Florencio Basaldúa, who wrote the following:


Breaking News from Lake Musters, reports the attack on the Mylodon by three expeditionary from the party of the former librarian of the La Plata Museum, and its escape due to the invulnerability of the monster's armour, and its aggressive rages; but it is certain that in the end it will fall prisioner of men.


The text quoted further up. Caras y Caretas, 1899

The librarian was Nicolás Illin, who in 1898 set out to hunt the Mylodon, it was one of several expeditions that were sent to search for the Mylodon. Illin also explored Lake General Paz (now Lake Vintter), but didn't find the creature.


Lake Musters is located next to Lake Colhue Huapi, which has its lake creature, and is fed by the Senguer River, where Muster's water tiger (the Iemisch?) was sighted.


Lake Musters is located in the steppe, it is an arid area, except for the water provided by the Senguer River and the lakes, little else is found here, only arid basaltic mesas, some salt flats and the Patagonian shrubs and tough grasses.


In June 1899, issue 35 of the magazine carried a political cartoon cover with a painting (see below) depicting hunters stalking a weird looking mylodon, that carried a British flag and had the word empréstito (loan) written on its fur.

Lake Nompehuen, gases?


Astrange effect of bubbles, anc concentric and waves was observed on a lake in Neuquén. It was filmed (see video below).


The incident took place at Lake Nompehuen, a small glacial lake (see it in Google maps) with a roughly square shape, 1 km by 1 km (0.6 mi). It is separated from Lake Ñorquinco by a narrow (400 m - 1/4 mi.) strip of land. It lies west of the town of Aluminé. The lake is fed by the river of the same name, and drains into Lake Ñorquinco.


The mysterious bubbles


Burst of bubbles on the lake.

Video on Instagram:



The bubbles appeared suddenly on the calm water on January 14, 2025. There are three possible explanations that were given for this event:


One, geothermal activity in this area, which is volcanic. The lake is located close to Lanin, Batea Mahuida, Solpulli, Quetrupillán and Villarrica volcanoes. Perhaps it vented carbon dioxide that accumulated in the bedrock beneath the lake bed.


The second possible cause is the accumulation of organic matter on the bottom of the lake, which due to climate change is broken down by bacteria into methane in the shallow waters, methane (the main component of natural gas) produces effervescence, and bubbly outbursts as they rise to the surface.


A third option is a "limnic eruption" or "lake overturn" where carbon dioxide from the deep waters is released in a sudden outburst. This takes place in deep lakes with cold water. The pressure of the overlying water dissolves the carbon dioxide (like in bottled sparkling water), and when the pressure is released the gas bubbles upwards. The trigger could be the warming of the waters, an earthquake or volcanic activity.

Lake Pellegrini


Lake Pellegrini, located in the steppe, in northern Patagonia is a reservoir, manmade, built in 1910-1915 to hold the flood surges on the Neuquén River and reduce the impact of floods in the Rio Negro Valley, that is located downstream.


The lake is 10 km to the northeast of the city of Cinco Saltos in the province of Río Negro, and roughly 25 km from the city of Neuquén (38°42'08.1"S 67°59'21.7"W).


There are two cryptozoology publications that cite a German scientist, Hans Krieg, as stating that there was a dinosaur in this lake.


1.In "Mysterious Creatures," George Eberhart states that "A dinosaur-like animal was reported in the 1930s, Hans Krieg." (source)


2.The Fortean Times also mentions Krieg and adds: "Referring to Lago Pellegrini, Krieg notes: "This beautiful lake was much talked about a few years ago this was a time of strange rumours in Argentina; from the south of the country, from the Andes lake Nahuel Huapi or from Lake Pellegrini and from the north, from the vast swamp lands at Laguna Iberá in Corrientes province, came exciting stories: a saurian, a living relic with grotesque looks, had been observed Some saw it flying , others swimming ; in any case it was an extremely strange creature . It appeared as in a dream and excited the people
[...]
I have mentioned one example of this dinosaur madness, which appears regularly, in connection with Lake Pellegrini in northern Patagonia, " he writes. " Here is a second one. In this case , we are not dealing with a mysterious gigantic lizard which surfaced from the depths and snorted , but with a stupid and awkward flying saurian , which was kind enough to appear in great masses on Lake Nahuel Huapi . One even fell under the mighty gun of a heroic What an enormously valuable object for science! What a pity the happy hunter, although he was convinced of his historic deed , cut only the head off and put it in his saddle bag. Twice as regrettable when we learn that he threw away this evidence after three days because he found the stench unbearable. He was certainly one of those tragic people who suffer grievously from the disbelief of their fellow men when, in old age - despite the scepticism of scientists, as they say - they tell their story to newspaper reporters . However, this hoax might have been a duck.At Nahuel Huapi and elsewhere one can encounter a duck called pato vapor (Tachyres patachonicus , King), one of the strangest among the few waterfowl of the lake. It is assumed that only a few It is assumed that only a few dozen individuals exist on the lake."
(source).


It seems to me that Krieg actually refuted it was a flying reptile, and stated it was a duck.


The lake was created in a natural depression (Cuenca de Vidal) and is roughly oval (24 km long, 12 km wide), with an area of 440 km2 Its average depth is only 9 m (28 ft.) and its maximum depth is 18 m (56 ft.) It stands in the arid steppe, roughly 250 m above sea level. This area has provided many fossils of dinosaurs from the final part of the Cretaceous Period some 65 million years ago, at the time they became extinct.


Lake Pellegrini. 1910 blueprint

The image shows the Neuquén River (bottom), and the basin (top), a dam cuts the river (Dique Ingeniero Ballester) which sends water into the main irrigation channel for the Rio Negro Valley (Canal Principal in the map), a channel links the basin and the river, and is used to send flood water into the lake. Below is a Google maps view (online) looking eastwards. Notice the irrigated areas, and the dry steppe.



Hans Krieg (1888–1970) had studied medicine at the University of Tübingen and zoology at the University of Munich. He earned both a Ph.D. and an M.D. He visited Patagonia in the early 1920s. Later he was appointed director of the zoological collections of the State of Bavaria and adjunct professor of zoology at the University of Munich. During the 1920s and 30s he took part in several scientific expeditions to South America. He was a member of the Nazi party from 1937 to 1945.

The pato vapor looks just like a duck, how could it have been mistaken for a flying reptile?

Creature in Lake Aluminé


Lake Aluminé is located in the central part of Neuquén in northern Patagonia, on the Andes, it is the last of the vast glacial lakes, of the land of the Araucaria monkey puzzle trees north of Lanin National Park.

It has a surface area of 57 km2 (22 sq.mi.) and a depth of 70 m (230 ft). It is linked to Lake Moquehue and is next to the Chilean border. It drains into the Aluminé River and its water reaches the Atlantic Ocean through the Limay and Negro rivers.

A Culebrón


In September 2019, some members of the Puel community (a group of Mapuche people) living in Villa Pehuenia, on the north side of the lake spotted something moving in the lake. They said it was like a water snake and it was seen swimming in golfo Azul (Blue Gulf) in the lake. It was filmed (video below, see it online), at around 7:30 pm on a calm lake.


Liliana Puel, a member of the community said that "there was a culebrón, there was one, but I think there were more" she added that "70 years ago in La Angostura (The Narrows) there was a ford where the horses were crossed, but they were not allowed to pass after sunset. Apparently, at dusk the culebrón was about. In those days there was no bridge, and they said that if the culebrón wrapped itself around the horse's leg, the rider would fall off."



 

As mentioned in my book, this lake is home to a strange fox-snake hybrid the nguruvilu. An article published in 1912, stated the following: "Doctor Lehman Nitsche obtained from Chief Nahuelpí a complete version regarding a certain nürüfilu, a monster in Lake Aluminé in Neuquén. There is no doubt that the nürüfilu is no other than Yemisch itself, and has, like him, a prehensile tail."


Anthropologist Paul Adolf Robert Lehman-Nitsche (correct name) interviewed the Mapuche chief in 1902, and it was then that the chief told him about the Mapuche myth of the snake-fox or “Nguruvilú.” The mythical Nguruvilú (also known as Nirribilo, Ghyryvilu, nürüfilu, etc.) derives its name from the Mapudungun words ngürü = “fox” and filu = “snake,” hence “fox- snake,” making it another Mapuche fox hybrid!


It was described in 1810 by Jesuit priest and naturalist, Juan Ignacio Molina, as a reptilian “Dragon”:

In certain Chilean lakes, an enormous fish or dragon can be found, which they name Ghyryvilu, that is, Vulpangue or fox-snake, which, they say, is man-eating, and due to this, they abstain from bathing in those lakes. They disagree on its appearance: some make it out to be long, like a serpent with a fox head.


A Culebrón is another type of creature, a large snake, thick and stubby, described as follows: "A big and snub-tailed snake, that is, with a truncated tail. On its back, it has a mane that measures up to two spans in length and that is extended on both sides, which it uses as wings to fly. The Culebrón’s size is variable; some specimens have been seen with a length of eight spans (1.60 m) [5 ft. 2 in.]"


And the Aluminé River, according to Clemente Onelli in 1922 had a huge beast. This river drains Lake Aluminé and receives the inflow of other Andean lakes (like the Pulmari, Ñorquinco, Rucachoroi, Quillén, and Tromen). It flows into the Limay River, which drains the Nahuel Huapi.

Fuegian palm trees, rhea and a penguin with scales


Tierra del Fuego is a large island on the southernmost tip of South America. It lies on the south side of the Strait of Magellan. It is shared by Argentina and Chile. Its name means "Land of Fire," due to the fires spotted by Magellan during the expedition, lit by the Selk'nam natives.


Its northern part is grassy, cold, and windswept, as you move south towards the Andes open forests appear and then, in the mountain range, dense, tangled Andean woods. Snowcapped mountains and glaciers line its southern flank. Freezing in winter, slightly less cold during summer.


However, the Dutch depicted it differently during their expeditions that took place in the early 1600s. They were seeking a way to the East Indies that didn't go through the Strait of Magellan, which was zealously claimed by Spain, or along the Cape of Good Hope in Africa. They explored Staten Island and found a way around the south side of the Island


The map below (online and zoomable) shows the ships of Joris van Spilbergen's expedition that navigated the Strait of Magellan in 1615. It depicts different scenes that took place in Tierra del Fuego.


Tierra del Fuego in 1615.

The image shows a penguin (marked with a letter "H") that is captioned in the text as follows: "H. Is a penguin, which are to be seen in great numbers there." Notice that it looks scaly rather than feathery! Then there is a tree that oddly resembles a palm tree (in the icy fireland!), further right there is a large bird being shot at by some Dutch sailors (caption reads "I. Are some sailors shooting birds on land.") The size of the birds is interesting. The penguin is as large as the natives. Is it some kind of giant penguin? If so, it became extinct.


The land bird to the right may be a ñandú or rhea, a flightless bird that inhabits southern South America and Patagonia, but nowadays is not found in Tierra del Fuego. Its size -as tall as the sailors- suggestss it was a rhea.


The Fuegian natives had a myth about the rhea, which they called "Ohi," indicating that it lived in the Island before it was hunted to extinction (read about this myth: the intriguing Ohi)

Boars swimming in Lake Nahuel Huapi


A surprising sighting took place on March 13, 2024 (source) when a fishing guide filmed a group of wild boars that were swimming in the lake and approached the boat he was in with some tourists. The video can be seen below.


The video is captioned: "Tourists surprised by four wild boars swimming in Lake Nahuel Huapi". Copyright LMNeuquen

These boars are not a local species, they were introduced from Europe into Patagonia to stock hunting grounds.


Seen from afar, would someone wonder if it was a lake monster?


I recall a personal experience that took place in February 1971, when my family camped in the forest lose to the Raquitue stream by Lake Huechulafquen in a wild setting. My parents had bought a box with 20 kg of apples in the Río Negro Valley during our 1.600 km (1,000 mi.) trip from Buenos Aires to Lake Huechulafquen. The Valley is packed with apple orchards, and they were the best apples I had tried in my life.
The day after we arrived, in the morning my Dad took the box -which was half empty- down to the lake and rinsed the apples, I asked why, if we had eaten them without washing them. And he told us that during the previous night a group of boars (which is called a "sounder") had intruded on our campsite and eaten most of the apples. Dad heard them grunting and munching apples and woke up, he frightened them away with his flashlight. My mother didn'l kie it at all, she wanted to move to a more civilized spot, so we uplifted our camp and went to an organized campsite at Bahía Cañicul. I was 11 years-old at that time and it was quite an experience!

Red deer swimming in Lake Nahuel Huapi


Lake Nahuel Huapi is the home of the mysterious Nahuelito creature, but also, has a varied fauna, both local and imported.


Deers can be mistaken for Lake Creatures


In July 2019, Tomás Isaurralde who was driving from Villa La Angostura to Bariloche along Ruta 40 highway, saw an unusual scene, a deer swimming in Lake Nahuel Huapi, close to a long fjord along its coast known as Huemul Arm.


As mentioned in my book:


Different objects may also be mistaken for lake monsters, such as fish swimming near the surface, bobbing logs, or long-necked birds.
Interestingly, early fall (March) is the red deer’s (Cervus elaphus) breeding season. During this period, called the rut, stags aggressively compete for the attention of the females (hinds).
Stags are also known to swim across the lake from Huemul Peninsula to Victoria Island searching for females, an open and exposed stretch 2 km (1.25 mi.) wide and over 200 m (655 ft.) deep.
An inexperienced observer would swear he or she had seen Nahuelito if confronted with a swimming deer in the middle of the lake.


Insaurralde filmed it and you can see the video online. Below is a still from the video:

Red deer swimming across a Lake Nahuel Huapi.

But, where did the red deer come from? They are a Eurasian species.


Argentine millionaire and dandy, scion of the Anchorena dynasty, Aaron de Anchorena (1877-1965) is a very charming character. He was an aviator, in the early days of aviation, and an enthusiastic big-game hunter. But above all, he was very rich.
He organized an expedition to Patagonia in 1901/02 to Chubut, Rio Negro, and Neuquén, during which he hunted sea wolves, guanaco, wild cattle, and wild goats.
He explored the region when it was still wild and mostly unknown. He immediately fell in love with it, and after visiting Victoria Island on Lake Nahuel Huapi, where he camped and hunted wild goats, he met Francisco Moreno and enlisted his help to secure ownership of the island.
By law, islands in Argentina belong to the Federal Government, so Anchorena couldn’t own Victoria Island, but he got a law passed through Congress (Ley 5,263) in 1907 that leased it to him for life.
He soon built a shipyard, planted crops, and introduced exotic plants, trees, and animals so that he and his friends could hunt them. Subjected to relentless criticism, he quit his lease in 1911 and purchased a plot of land nearby, on the Huemul Peninsula, which he owned with his nephews and niece, the Ortiz Basualdo.
The interesting part of this story is that he brought into what is now a National Park, animals from other parts of the world and set them free on the island; these were red and axis deer, wild boar, pheasants, and brown bears.


He also introduced European wild boars to his ranch at Huemul, which later (1999) swam across Lake Nahuel Huapi, returning to Victoria Island.


On the Huemul Peninsula, Anchorena built an imposing ranch house was built in wood and stone in a style that would be adopted by architect Exequiel Bustillo and used in the Bariloche Civic Center and administrative buildings. The Prince of Wales stayed here in 1931. It was also the site of the first Jesuit mission established by Father Nicolás Mascardi on the coast of Nahuel Huapi in 1670.

Lake Huechulafquen


The journalist that covered the Plesiosaur expedition in 1922, sent by the Buenos Aires magazine Caras y Caretas interviewed a Mr. Goicochea who had lived in Minas (central Neuquén province) about other sightings. Below is what he reported in issue 1229 (April 1922).


The Plesiosaur in Lake Huechulafquen


The text in English is the following:


Mr. Goicochea said "I remember, when I was the Secretary of the Court in the Department of Minas, hearing many times, [from] respectable neighbors something similar to that... and they were not young fellows... I will cite their names: Mr. Cecilio Gerio, merchand in Junín de los Andes, Mr. Mendaña, old rancher of those regions, one of the first settlers in the Cordillera... Another: "Fair" Bagual, which is his nickame, but is really named Rodriguez... Well, this Rodriguez was a soldier in the expedition to the desert. He deserted and then obtained his retirement and now owns a small ranch over there... All of them have said many times that in the lake Huachi-Lauquén [sic] at sunset, an animal often appewars on the surface of the water, with more or less the same features of the one they say they have seen in Esguel [sic]. Very long neck, head of a lizard, the body that must be enormous, because when it submerges, it produces like a boiling in the water


Huachi-Lauquen is Lake Huechulafquen, and Esguel, is a small lake close to the town of Esquel in Chubut.

Huechulafquen is a large lake, 30 km (19 mi.) long and up to 5 km (3.1 mi.) wide, it covers an area of 78 km2 (30 sq. mi.), and is very deep.

Lake Huechulafquen and Lanin Volcano by the northeastern tip of the lake

In the 1960s, Gregorio Alvarez casually mentions among several other strange mythical animals which he calls zoomorphs, a “cow at Lake Huechulafquen.”Unfortunately, he did not describe the beast, so its appearance is a mystery.


In March 2009, a tourist named Jorge Salcedo, while on an excursion in a catamaran, photographed what looks like a set of three waves that look more like the wake of some boat than the back of an animal swimming just below the surface. The media quickly reported it as a lake creature and named it “Huechulito.”


In 2023, a tourist filmed some strange waves in the calm lake (Source). Below is a still from the video (video online).

A plausible explanation could involve otters or even gas bubbles surfacing in the lake because there is plenty of geothermal activity and hot water springs in the area as it is located beside the Lanin volcano.


Lanín is a stratovolcano, that is 3,747 m (12,293 ft.) high, it has a conical shape and its summit is covered by glaciers. It last erupted around 1,500 years ago.

Pyrassouppi: a horned guanaco


André Thevet not only described the succarath in Patagonia, he also mentioned a horned creature in the River Plate region in his book La Cosmographie universelle, published in 1575.


In it, he inserted it as a comment while mentioning the Island of Cadamoth on the Red Sea and unicorns, probably recalling his adventures in Brazil. The marginalia printed by the entry reads, “Pyrassouppi, beast as large as a mule.


As you can see in the image below, it has sharp and straight horns and curly, long hair.

Pyrassouppi. Thevet, (1575). La Cosmographie universelle.
Pyrassouppi: a horned guanaco?

The image shown above accompanied his description. It depicts a South American native with a “bola perdida” type of boleadora hunting one of these creatures.


The "Bola Perdida" was a type of boleadora was used as a mace in a melee, to strike the opponent or prey, and as a throwing weapon, like a slingshot, it could kill or maim the target up to 100 m (300 ft.) away. "Boleadoras" on the other hand, had multiple "balls". The name boleadora derives from the Spanish word bola (ball). These were stone balls sheathed with leather and attached to strong tendon straps that were whirled above the head of the hunter to gain momentum and then thrown to entangle around the hunted animals’ legs.


In the image, a pyrassouppi is being flayed in the background. The natives are clad in skins, like the Patagons.
Thevet wrote:


In the province, which is along the river Plate, there is a beast that the savages call Pyrassouppi, as big as a mule, and its head almost similar, hairy in the shape of a bear, a little more colored, tending towards the tawny, and having cloven feet like a deer. This Pyrassouppi has two very long horns, without antlers, very high and which approach those unicorns so esteemed … The portrait of which I have been kind enough to represent to you here in the natural state, and the manner in which these barbarians use to kill it, namely with large iron balls, weighing ten to twelve pounds, attached with sinews of other wild beasts at one end and the other to their arm. Of which they also eat the marvelously good flesh.


The beast has a Tupi-Guaraní-sounding name and resembles a cross between an antelope and a guanaco. Antelopes are bovids, and they are mostly found in Eurasia and Africa, with one extant species in the Americas, the North American pronghorn.


None live or seem to have lived in South America.


There is a myth among the Inca and Andean people, the Llastay (or yastay, also called coquena), son of Mother Earth (Pachamama), described as an old man with a long beard and horns. He is the guardian of wild animals, especially guanacos and vicuñas; he is the god of hunting, and lives in a shack built with “guanaco bones covered with their horns.”


But guanacos don’t have horns! Even though their distant relatives, the protoceratids, an extinct group of North American antelope-like herbivores that lived during the Eocene to Pliocene epochs (46–4.9 Ma.) had bony horns.


There is a horned guanaco-like creature, but without the woolly fur. A South American type of deer, the brocket, of the genus Mazama. They are relatively small and include around ten species, some of which are found in Brazil, Paraguay, Uruguay, and Argentina in the “monte,” a region with scrubland and open forests at the edge of the prairies. Their unbranched antlers are small and resemble spikes. In appearance they are more deer-like than the guanaco camelids.

Seal at Lake Ranco, Chile


An article published online in the Chilean Diario Futrono on Oct. 6, 2024, (link), reported a sighting of a South American Fur Seal (Arctocephalus australis)) in Lake Ranco.


Lake Ranco lies at a very low elevation, only 65 m (213 ft.) above sea level, and has a surface area of 442 km2 (171 sq. mi.) It is notorious for Culebrón and Cuero sightings. It drains into the Pacific Ocean through the 200-km-long Bueno River (124 mi).


In March 2023, there was a sighting in the lake (with a video to prove it). A local marine biologist at the Santo Tomás University in Osorno, Chile, Alexis Santibáñez, believes it is a sea wolf. He had seen them in the past swimming up the Bueno River, chasing Chinook salmon as far as 70 km (44 mi.) from the sea.
